I used the world realistic to separate the base designs in cause from the slaughterhouses players build, I believe that was fairly obvious. As in, something that someone could live in (not necessarily real life) and have permanent entrances, not entrances that you get to by placing down 2 frames and removing them, but anyways.
Well, my first base in A19 was made from the destroyed house PoI with the water filled basement (has an ammunition box inside the water) and was holding up pretty well, until zombies "found" a weakness (literally the same blocks throughout the whole house, but these were slightly damaged) in the opposing side where they were originally coming from, and their hive mind AI simply sent them into attacking those 2 single blocks.
And no, not everything has to work, but practical things that look good and are built to protect, should continue to be viable strategies. The example you said "pole sat on", is one of the things that in fact YOU SHOULD remove...Oh and i did have working designs on A17 and A18, otherwise I probably wouldn't be playing the game. The point here is not to see what works, but to ask yourself why don't the others work, when they obviously should? I'm not putting in cause the bases that work, that has never been my point, I merely questioned why do they keep working, but the others don't.
Oh and when you have double walls, triple, quadruple, you really SHOULD have it working. But as for someone who is putting concrete walls simply to direct them to the BIG *SS open entrance and mitigate focused damage, it's kinda frustrating when they prefer to break 2 blocks instead of going through an open area with traps (yes, zombies don't know what traps are) or each attack different spots at the same time.
But hey, each to their own, i'll make my own final judgments when the game finally comes out.
